Atmospheric vertical velocity - a crucial component in understanding proximal deposition of volcanic ash
•A weak eruption at Sakurajima was studied using high-resolution modelling.•Atmospheric vertical velocity (w) was key in recreating observed sedimentation.•Not accounting for w led to a 2-5 m s−1 discrepancy in the fall velocity estimation.•Mountain waves can enhance proximal deposition of fine ash...
